DraggableView

A lightweight draggable view.

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Installation

DraggableView is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'DraggableView'

Usage

The usage is simple as creating an instance of a basic UIView 😄.

var draggableView = DraggableView()

// The padding value that it will stay far from the edges
draggableView.padding = 16

// The threshold value defines the velocity on both x and y axis.
// After draging the view, the view will position itself according to
// the x and y velocity if the threshold condition is met.
// Othwerwise, it will position itself to the nearest corner. 
// See the source code on how it positions itself. 
draggableView.threshold = 1500

UIViewController Example

import UIKit
import DraggableView

class CustomView: DraggableView {
  // Your custom codes...
}

class ViewController: UIViewController {
  
  let draggableView = CustomView()
  
  override func viewDidLoad() {
    super.viewDidLoad()
    setDraggableView()
  }
  
  func setDraggableView() {
    draggableView.translatesAutoresizingMaskIntoConstraints = false
    draggableView.backgroundColor = .darkGray
    
    view.addSubview(draggableView)
    
    draggableView.padding = 10
    draggableView.threshold = 1500
    
    let screenSize = UIScreen.main.bounds
    
    NSLayoutConstraint.activate([
      draggableView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: draggableView.padding),
      draggableView.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -draggableView.padding),
      draggableView.heightAnchor.constraint(equalToConstant: screenSize.height * 0.4),
      draggableView.widthAnchor.constraint(equalToConstant: screenSize.width * 0.5)
      ])
  }
}
